To detect these issues, loop and MAC flap detection is available on Meraki switches. Thanks to the dynamic learning feature, you do not need to type any MAC address.
Resource Error: High CPU utilization may cause inadequate BPDU transmission, Packet Corruption: High rate of packet corruption may cause BPDU loss, One of the easier solutions is to enable STP that protects against layer 2 loops and most of the time it works well however if there is BPDU loss then layer 2 loop is inevitable. One of the biggest challenges with redundancy is that it can introduce loops, which can cause a broadcast storm. This makes maintaining a network harder as the network continues to grow to accommodate more users and applications. Redundancy reduces downtime in the event of a link or network device failure but sometimes it can lead to complex network design. show mac-address-table To display the MAC address table, use the show mac-address-table command in privileged EXEC mode. I do have I.P addresses in another area, but they are not in the spreadsheet I am working off of so I was hoping to use only the mac address.
The show mac address table interface x/x/x also returns nothing.
